I am checking if build restart will help

[antnieszka]

I did it once, and it didn't help :(

[grzanka]

Change to 2 workers and let us see

[grzanka]

May it be an issue with newly released Sphinx ? https://pypi.python.org/pypi/Sphinx
You can also try to run sphinx in Python 3.5 instead of 3.4

[antnieszka]

By workers You mean sphinx-build jobs? We have 4 if I'm looking at the right piece of code.

But new sphinx was released (wheel uploaded) 2016-12-05. And it started failing today :/

sphinx-build -j2 ... let's see now...

I'm trying to debug it locally - it also fails:

Exception occurred:
  File "/home/ant6/PycharmProjects/beprof/.tox/docs/lib/python3.4/site-packages/docutils/writers/_html_base.py", line 671, in depart_document
